Answer:
50% of getting A blood type
Explanation:
Using a punnet square you have (sorry cant do a square)
<u> IA IB</u>
<u />
<u>IA</u>
<u />
<u />
<u>i</u>
<u />
Then you you add all the possible combinations from both parents genes
IA IB
IA IA IA IA IB
i IA i IB i
You now have a 50% chance of A type blood because the lowercase (i) wont change the blood type outcome because the IA over shines it.
A. Stretching your legs before a run. You're creating tension by applying force to pull your tendons and ligaments.
Transcription factors are necessary for an initiation of transcription at a regulated gene but not sufficient.
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter Transcription factors can enhance the interaction between RNA polymerase and a DNA sequence- promoter, encouraging the expression of the gene. Such transcription factors are called activators. Otherwise, when the gene expression is inhibited, factors are called repressors and they bind to sequence –operator.
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex
Answer: Option A
The primary function of DNA polymerase is to add nucleotides to the growing daughter strands.
Explanation:
DNA polymerase is an enzyme that synthesis DNA and its main function is to make DNA from nucleotides which is the building block of DNA. It is essential for DNA replication and work in pairs by creating identical DNA strands from the original DNA molecule. DNA copies are created by pairing the nucleotides to each bases present in the DNA molecule.The bases are thymine, cytostine,guanine, and adenine, the pairing occur with any of the above combinations forming two pairs respectively.
